• ### Analysis of power draw in ball mills by the discrete

Apr 01, 1999 The calculated power draft is maximum at about 50 ball load. According to Eq. 1, mill power is a function of ball mass M b and the distance between mill center and the center of gravity of ball mass r g. So, as the mill filling increases M b goes up, but r g decreases. Therefore, the power draft passes through a maximum.
